M151 High Current Calibrator

Product catalog summary

Overview: The M151 is a high current calibrator designed for precise calibration tasks, supporting both AC and DC currents ranging from 8 mA to 120 A, with a frequency range of 15 Hz to 1000 Hz. It offers a total accuracy of 275–400 ppm across all ranges and features a floating output up to 450 Vpk.

Key Features:

Calibration of clamp meters up to 3000 A using a current coil.
Real and simulated transconductance amplifier capabilities.
Standard interfaces include GPIB and RS-232 for control and communication.
Internal recalibration procedure accessible from the front panel.

Specifications:

General Data: Warm-up time is 15 minutes, with operating temperatures between 5 °C and 40 °C. The device weighs 42 kg and supports power supply of 115/230 VAC at 50/60 Hz.
DC/AC Current: Offers a current range from 8 mA to 120 A with a resolution of 5¾ digits. Frequency accuracy is 0.005% with synchronization options.
Multimeter Functions: Includes AC and DC voltage and current measurements with high accuracy, and frequency measurement from 1 Hz to 10 kHz.

Performance: The calibrator provides a distortion level of less than 0.1% and maintains output terminal isolation up to 450 Vpk against ground. It supports a simulated amplifier gain of 0.5 – 10 A/V and 50 – 1000 A/A.

Additional Features: The M151 can be used with a current coil (151-25) to achieve a maximum simulated current of 3000 A, with an additional uncertainty of 0.3%.

Current Calibrator AC / DC current 8 mA…120 A, 15–1000 Hz Total accuracy 275–400 ppm in all ranges Floating output up to 450 Vpk, compliance voltage 8 Vpk Calibration of clamp meters up to 3000 A Real and simulated transconductance amplifier GPIB and RS-232 come as standard Model M151 is a stable high current calibrator up to 120 A. Basic accuracy is 275 ppm. Instrument can be controlled via RS232 or GPIB interface. Calibrator can work in a simulated amplifier mode to increase current ranges of any multifunction calibrator. It is suitable for power meter’s calibration because M151 can be synchronized with the input signal not only in amplitude but also in frequency and phase. Current terminals are isolated up to 450 Vpk against case (protective earth). M151 is a sophisticated instrument with its own recalibration procedure. The procedure enables to adjust any deviation directly from the front panel. Calibrator is designed for checking parameters of amp meters. With current coil it can be used for calibration of clamp meters. Zelezna 3 | 619 00 Brno | Czech Republic | 420 543 250 886 | [email protected] | www.me
